The present application belongs to the technical field of water conservancy and
hydropower engineering closure construction, and particularly relates to a kind of embankment closure method based on integral
assembly type double
ridge closure bottom protection structure.The present application precast and accurately throw the integral bottom protection structure formed by rigid connection of bottom protection section and double
ridge section in
dry season of a year before closure, with standardized reinforced
gabion as basic unit, adopt double connection inside and outside to form continuous plate type whole, with high
impact resistance and stone blocking foot capacity.Through particle size and
impact distance calculation, throw test, GPS joint positioning to realize accurate
underwater throwing.After bottom protection construction is completed, embankment pre-advance is implemented in
dry season of next year, and large stone and reinforced
gabion are continuously thrown in closure stage, which can improve the stability of throwing material, prevent embankment collapse, and realize safe and rapid closure.The present application can solve the problems of traditional dispersed bottom protection, such as easy loss, low precision, interference with
flood discharge, etc., and greatly improve the safety and efficiency of closure under complex riverbed conditions.
